Who can rebuild my trans to handle 800 rwhp? Im done with amcco. Im on my 5th rebuild, valve body is sticking

 

If you're serious about making a reliable FI drivetrain, quit wasting more money on a 60 and get a low mile 80E, install a Transgo HD2 shift kit, and get a good converter like a Yank. If your not on a budget get a 80 built from a sponsor like Jakes.

 

No one can make it last at that power level. Maybe with a 2500lb car it could work.

 

We use and sell RPM Transmissions. Check one of our GTOs seen here in this video. It makes 830rwhp through their Level 6 4l60E. We have ran over two seasons and hundreds of passes at the track without a flaw. Let us know if we can help you out with it.

Thanks-

From what I hear, the 80e can hold 800hp with just a few small mods. That beats paying 4000$ for the level xx 4l60e. Converting over just requires a new converter, a new or modified cross member, a 120$ harness, and, a little tuning from hp tuners / whatever you use.

 

X2. At those levels, its not "if" but "when".

As mighty mouse said, the only thing he is 100% confident in not breaking in his whole car is his 4L80E.

 

Yeah buddy, I don't think Amcco is going to get the job done.... I have seen guys take junkyard 80E's with new converters and put nitrous on em and not break em.......

go 80e.. i was debating the same thing that you are.. i have a 65 chevelle ls2 single turbo, and bought a nice used 4l80e and sent it out and had it built and now driving the car with it i love it

 

I have a Rossler T2 4L60E, and as much as I don't believe it will go at the power i'm at now. If it was to go I think I would switch to an 80e.

 

OP just think of it this way......

4l60= 700R4 (electronic/internals modified/OD)
4l80= TH400 (electronic/internals modified/OD)

Now yes the 4l80e will be more parasitic due to the mass and weight of internal parts, but that is a compromise of durability.

Now what would be great if they built a TH350 with OD/ electronically controlled.... I would be all over that, less parasitic but would run like hell. I had a TH350 a few years ago with a shift kit and I beat it like it stole something and it never slipped or missed a beat.. A lot of diehard racers prefer TH350's over Th400 due to less parasitic loss and weight.

I said all of this just for conversation purposes, but I am sure a well built 4l60 can be built to last, but its going to cost ya.

Rpm has the best luck with 4l60e's, IMO.

 

RPM, this is Arun's 4L60E-car is no LW either, full weight, AC, power everything, pump gas-last time we weighed it it as like 3600 some pounds.

Last time I talked to him he's gonna try some things nobody's tried with a 60 and hopes to run 8.8's@160!

 

If your serious about making big hp with a 4l60e, call up Carl Rosller@Rossller trans !
